BALlNG-PRESS- SPECIFICATION forming part of Letters Patent No. 763,005,vdated June 21, 1904.

Application filed August 10, 1903. Serial No. 168,890. (No model.)

To all whom, it 7de/ty concern:

Be it known that L HERMAs LARosE, a subject of the King of GreatBritain, residing at Vercheres, county of Vercheres, Province of Quebec,Canada, have invented certain newV and useful Improvements inEaling-Presses; and I do hereby vdeclare that the following is a full,clear, and exact description of the invention, such as willenablexothers skilled in the art to which it appertains to make and usethe same.

My invention relates to balingpresses adapted to pressloose material ofvarious sorts such as hay, cotton, cornstalks, hair, shavings, chips,and the like-into bales, one of the objects to which my improved pressis especially adapted being compressing wooden chips. t

The object of my invention is to produce a press of the reciprocatingtype, which has a positive motion in both directions and combines themaximum amount of compression upon each stroke lwith the maximum powerused in the said compression, said power being applied at those pointswhere it is most needed.

One ofthe special features of my invention lies in the means whereby Iprovide a press, compressing the material in both directions and indiiferent chambers, in combination with `means for transferring thepartially-compressed material in the state of partial compression inwhich it is left by the first operation from the [irst'ehamber into thesecond, in which the compression is completed.

My invention further consists in the construction and combination ofparts,hereinafter described, and more particularly pointed out in theclaims following this specification.

1 have illustrated in the accompanying drawings the preferred form of myinvention as applied to the compression of chipsA and also a modifiedformparticularly adapted for use for compressing loose bulkymateriaLsuch as hay, and herein# Figure 1 is a plan view of the firstform of my improved press. Fig. 2ois a side' elevation of the waistportion thereof. Fig. 3 is alongitudinal central section throughthesame.

Fig. 4 is a transverse sectional elevation taken on the line 4 4 of Fig.8. Fig. 5 is a fragmentary longitudinal section similar to Fig. 3, butshowing parts in a diiferent position. Fig. 6 is afragmentarycross-section through the sliding charger of the apparatus.l taken onthe line 6 of Fig. 5. Fig. 7 is a longitudinal central section throughthe apparatus similar to Fig. 5, but showing parts in a diiferentposition. Fig. 8 is a .fragmentary plan section taken on the line 8 8 ofFig. 3. Fig. 9 is a side elevation of the above-mentioned modified formof the invention adapted for the' vcompression of hay. Fig. 1() is alongitudinal section through the same machine.

The same numerals of reference denote like parts in all the figuresofthe drawings.

Referring first tothe form Vof the machine shown in Figs. 1 toI 8,inclusive, 11 designates a longitudinal chamber of any ordinary orapproved pattern, having sides 12 open in the rear portion, as shown at13, and provided with slats 14 to confine the material undercompression, as in the usual press of this type. In this chamberreciprocates the plunger or trunk 15, which has antifriction-rollers 16,pivotally mounted at its lowest side and upon which it rolls along thedoor of the chamber 11. At 17 are shown any suitable springcatch devicesfor preventing material being compressed from backward movement. Abovethe chamber 11 is located a sliding charger 18, and above this is fixeda stationary hopper 19, of the form shown and into which the material tobe compressed is fed during the compressing operation. The mouth of thishopper 19 is not directly over the chargingopening 2O of thecompression-chamber 11, f

but at one side thereof, and the reciprocating charger 18 has a tubularreceptacle 21, which is of the same sectional varea as the opening 2Oand the mouth of the hopper, and this is arranged to reciprocate betweenthe mouth of TOO sists of -a train of gearing mounted on the main axle24 and the two secondary axles 25 and 26. The main axle at 24 has lixedthereto a driving-pulley 27, which is adapted to be operated from anysuitable source of power by means of a belt 28, and it is journaled inpillow-blocks 29 at each side of the framework of the machine. On theouter side of each pillow-block is carried a small gear-pinion 30, andoutside of this on each end of the axle are mounted two heavy fly-wheels31. The secondary axle is sustained on pillow; blocks 32, formed on aframework near each end of the axle, and it carries on each end thereofoutside of the pillow-blocks a large gear-wheel 33, the two gear-wheels33 being arranged to mesh with the two pinions 30 on the main axle 24,and within the two pillowblocks 32 are mounted two small gear-pinions34. The tertiary axle 26 is likewise `mounted in pillow-blocks 35 on theframework and carries within these pillow-blocks apair of largegear-wheels 36, which mesh with and are driven by the pinions 34. Asthis axle sustainsthe direct pressure of the plunger 15 in thecompression process, it is made larger and stronger and more solidlyfixed than any of the others, as indicated in Fig'. 1. With the twogear-wheels 36 is operatively engaged the plunger-rod 37, which has atits forward end a cross-head 38, this consisting of a solidly-fixed pinextending on each side into oneof the pair of oppositely-disposed slots39, which are formed at an angle somewhat oblique to the radius of thewheels 36 by 'the peculiar shape of some of the spokes thereof. Only oneslot of each pair is used at a time, and the other slot is idle, theonly purpose of this being to prolong the life of the wheel by utilizingthe other slot when the first slot is worn out. It will be seen from themode of connection described that the plunger-rod 37 has a certainamount of loose or free motion relatively to the wheel 36; but thecross-head 38 of the plunger-rod is further guided by a pair ofcam-blocks 40, which are of the shape shown best in Fig. 3 and on thelower forward side of the wheel. These blocks 40 are engaged by theprojecting ends 38 of the cross-head, which extends beyond the planes ofthe wheels 36. The motion of the cross-head and the plunger-rod carryingit is further limited by two cam-bars, (designated, respectively, 41 and42,) the action of which will be presently described. Coacting with thefirst pair of cam-bars 41 is a camroller 43, which is carried by a pairof offsets 44 on the lower side of the plunger-rod 37.

Supposing the plunger is at the beginning of its forward stroke-that isto say, in the position shown in Fig. 3-the cross-head is at the outerend of the slots 39, being kept in this position by the engagement ofthe ends 38L thereof with the circular concentric surface 45 of thecani-blocks 40. As soon, however, as the ends 38a pass beyond the upperpoint of these circular' surfaces they are rcleased, and the cross-headstrikes the cam-bar 42, which throws it gradually inward toward theinner ends of the slots 39-that is to say, close to the center of thewheel. During this time the compression of the material is slight, andthe compressive force needed to advance the plunger is correspondinglyslight, so that the slight power employed by reason of the interactionof the cam-bar 42 and the slots 39 is suicient to advance the plunger tosuch an extent. When, however, this is accomplished, the compression hasproceeded so far that more force is needed to more completely compressthe material and enable the plunger to linish its stroke, and thereforethe cross-head is retained at the inner or hub ends of the slots 39 bythe cam-bar 42 until after the slot has passed the vertical position,when the reaction of the compressed material retains it in this positionthrough an angle of about one hundred and eighty degrees. As therotation proceeds and the plunger is drawn back the ends 38 of thecross-head now strike the oblique vcam-surfaces 46 of the blocks 40, andthis forces .the cross-head again to the outer or circumferential endsof the slots 39 until the roller 43 strikes against the cam-bar 41,Which causes the said motion to be a gradual one and prevents the suddenjar of the crosshead upon the ends of the slots 39.

By the above description it will be seen that the greatest power duringthe revolution is applied during the greatest compression of thematerial and that the advancement of the plunger during the period ofeasy com pression takes place rapidly.

I will now describe the mode of operation of the charger 18, which isreciprocated direct from the plunger 15 and has a disengaging device toenable it to be thrown out of service temporarily whenever desired. rlhecharger 18 has connected thereto a bent linkframe 47, which has an Hform comprised of two longitudinal bars 48, connected by a crossbar 49,and the ends of the bars 48 are pivotally connected, as at 50, to thecharger. The bars 47 have formed therein to the right of the cross-bar49 semicircular notches 5l, which arev adapted to be engaged by anupstanding lug or strap 52, iixed to the upper side of the plunger, asshown. In Figs. 3and 5, in which these lugs are engaged with the notcheson the bars 47, it will be seen that the charger 18 partakes of themotion of the plunger and reciprocates synchronously therewith, and inthis case the material is fed into thel hopper 19, and at each backwardstroke of the piston a portion thereofl is carried by means of thereceptacle 21 and dropped through the opening 20 into the compressionchamber. I 1n some cases, however, when it is desired tol throw thefeeding apparatus temporarily out of use I make use of a disengagingpiece 53,

becomes stopped up and it is desirable to ob` tain access to the mouthof the compressionchamber without stopping the whole machine. In somecases also it may be desirable to feed the chips directly into the mouth20 'of the compression -chamber without the intermediary of thereciprocating charger.

In Figs. 9 and 1() is shown a somewhat different form of machine whichhas a double compressive function and is especially adapted for loosespringy material, as above stated. The compression-chamber 11, theplunger 15, plunger-rod 37,and all the parts generally connectedtherewith are precisely as in Fig. 3, with the exception of the hopper'and reciprocating charger, which are dispensed with and replaced byother devices, and also with the exception of certain appurtenancesconnected therewitlnwhich will be described. At the right-hand side ofthe mouth of the compression-chamber there is a stationary plate 57,which extends upwardly a considerable distance and forms a stationaryabutment for the primary compression of the material, which is effectedby means of a reciprocating box-like structure- 58, which Vis connectedat the sides to the plunger 15 by means of strips 59 and a securing-post60. The mode of operation of this arragement will be made evildent, asit will be seen that the reciprocating member 58 by alternatelyretreating from and approaching to the abutment 57 forms a boX or hopperof variable size, which is practically a primary compression-chamber,the hay being fed into itwhile the plunger is at the forward orleft-hand end of its stroke and being compressed on its return motion.When the plunger and reciprocating member 58 have contemporaneouslyreached the right -hand end of the stroke, the partially-compressedmaterial 6l is thrust down through the opening 2O by means of apusher-board 62, which is pivotally mounted, as at 63, upon the end -ofa long lever-arm 64, pivoted at upon the frame of the machine. Thislever-arm 64 is oscillated about its aXi's at the proper time to thrustthe pusher 62 down into the position shown in dotted lines in Fig. l0 bymeans of a trip-bar 66, which is pivoted to a pair of bearing-irons 67,carried by the lever-arm, as shown, and whose lower end projects into aposition to be engaged by a lug 68, projecting beyond the cross-head onthe plunger-rod 37, which acts to push the trip-rod upwardly,

Anormal position.

and thus thrust the pusher 62 downwardly. The pusher-board 62 is held invertical position during its downward movement by a bridle-bar64n,`connecting the upper end of the pusher above the pivot 63 with aprojecting portion of the frame.- Ordinarily the lcver-arm is held inraised position by a counterbalance-weight 69, mounted on the rear endof the lever-arm 64. After the Amaterial has been thrust down into thecompression-v chamber by means of the pusher, it will ordina'rily returnto its normal position, as shown in full lines by the saidcounterbalance; but as it may on some occasions become 'stuck in thematerial thrust into the compressionchamber positive means is providedfor raising it, so as to prevent it from becoming caught between theplunger 15 and the wall of the opening 2O and so breaking or derangingthe apparatus. This means comprises a triangular projecting cam-bar 70,which is fixed to the lower side of the rod 64 in position to be engagedby the .upstanding connecting-iron 60 on the plunger, and thus it ispushed out of the plunger chamber sufliciently to become disengaged andresume its As in some cases it may be desirable to throw they ypushertemporarily out of action' in order to permit inspection or other workaboutthe press, I have further provided a disengaging device comprisinga plate 71, which is reciprocably mounted in guides 72 at the forwardend of the frame and has a hole 73, through which the bar 66 passes, andthis plate 7'1 is connected by a link-rod 74 with a stationary abutment57, or rather with a hand-lever 75, pivoted at its ends upon a bolt 76,set in a pair of projecting lugs 77, fixed to the said abutment 57. Thehand-lever 75 may be provided with a weight 7 8, so as to hold it in theposition in which it is vfixed; but it is adapted toy/be thrown intoeither of thetwo positions shown, rcspectively in full and dotted linesin Fig. 9. In the full-line position it will be seen that vthe plate 71is drawn back, so as to throw the trip-rod 66 into position to beengaged Yby the lug 68-that is to say, into operative position for thepusher 62-but when thc handle 75 is thrown over into the position shownin dotted lines the pusher 66 is turned, so as to be no longer engagedby the lug 68, as shown by the dotted lines in Fig. 10.

It will be seen from the last-mentioned form that a press is providedhaving a double compression, this taking place on both forward andbackward strokes of the plunger, and for this style of press thecam-blocks 4() are par- IOO IOS

self to the precise form shown, for many of the details may be changedin form or position without affecting' the operativeness or utility ofmy invention, and I therefore reserve the'right to make all suchmodiiications as are included within the scope of the following claimsor of mechanical equivalents to the structures set forth.
